Title: Image forming device
Inventor: MAEDA MASATAKA
IPC: B41J2/385
Filed: 1990-10-17
Abstract: PURPOSE:To improve controllability of toner flow modulation to enhance a pixel forming speed, a pixel density, and gradation properties by a method wherein a counter electrode having the same electric potential as a reference electrode is so disposed as to be proximate and opposed to an aperture of the reference electrode. CONSTITUTION:A toner positively electrified by friction with the rotation of a brush roller 20 and a supply roller 23 is fed by the brush roller 20. The toner filliped by a blade 24 is guided by a guide plate 25 and supplied between a reference electrode 3 and a reference counter electrode 5. By applying a negative voltage to a control electrode 4 on an image signal, an electric field having electric lines of force directing from the reference electrode 3 and the reference counter electrode 5 to the control electrode 4 is formed inside and below an aperture 6. The toner is attracted outside from the rear surface of an aperture electrode 1 by this electric field and held on a support body 10 by a fly electric field formed by a back electrode 11 to form a toner image part thereon. Since a maximum value of the electric field below the aperture and thereabouts can be enhanced, a toner flow controllability is improved, and a pixel forming speed, a pixel density, and gradation properties are enhanced.

Title: Gas flow rate controlling device
Inventor: MORI YOSHIFUMI
IPC: H01L21/205
Filed: 1984-12-29
Abstract: PURPOSE:To enable to sharply change the flow rate of gas sent from a bubbler sharply by a method wherein the first gas flowing path connected to the bubbler and the second gas flowing path, whereon a fixed quantity of gas is flowed at all times, are provided and the second gas flowing path is connected to the flow-in side and the flow-out side of the valve of the first gas flowing path through the intermediary of the valve. CONSTITUTION:The first gas flowing path 3 connected to a bubbler 1 and the second gas flowing path 4, whereon a fixed quantity of gas flows at all times, are provided and the second gas flowing path 4 connected to the flow-in side and the flow-out side of the bubbler 1 of the first gas flowing path 3 through the intermediary of valves 7 and 8 respectively. The flow rate of gas sent from the bubbler 1 can be sharply changed by switching the valves 7 and 8. For example, when the carrier gas flow rate of the first gas flowing path 3 is set at D and the carrier gas flow rate of the second gas flowing path 4 is set at E, the flow rate of gas sent from the bubbler 1 becomes D during the period F when the valve 7 is closed and the valve 8 is opened. Then, when the valve 7 is opened and the valve 8 is closed, the flow rate of gas sent from the bubbler 1 becomes D+E. Moreover, when the valve 7 is closed and the valve 8 is opened, the flow rate of gas sent from the bubbler 1 becomes D instantaneously.

Title: Rotary actuator
Inventor: TOJO EIICHI
IPC: H02K1/27
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To provide a rotary actuator, wherein a magnetic member for covering the permanent magnets of a rotor can be secured using a simple structure and torque generated is not reduced. SOLUTION: A cylindrical member 35 is in contact with a joint section 36 formed between permanent magnet groups 33, 34 on the circumference of a rotor core 32, and with projections 32b formed in the central portions of the permanent magnet groups 33, 34 and is fixed by press fit so as to cover the permanent magnet groups 33, 34. A magnetic throttle section 36a, the cross-sectional area of which is smaller than the cross-sectional area of the joint section 36, is formed as magnetic reluctance section between the joint section 36 and the cylindrical body of the rotor core 32.  Since the cylindrical member 35 as a result is secured on the rotor core 32 with stability, it is made difficult for magnetic flux to pass through the magnetic throttle section 36a, even when the rotor core 32 is in contact with the cylindrical member 35 at the joint section 36 across a wide area, and the magnetic flux is magnetically saturated. Consequently, the leakage flux can be reduced, and the torque generated can be prevented from being reduced.

Title: Driving device for spontaneous luminous display
Inventor: SHIGETA TETSUYA
IPC: G09G3/28
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To decrease false contours by changing the light emission pattern of pixel data corresponding to every one pixel to another light emission pattern when any one of respective pieces of pixel data corresponding to each of the plural pixels adjacent to the pixel varies in the logical values of its high-order bits from each other. SOLUTION: A high-order bit inversion detecting circuit 31 detects whether the logic of any one bit among respective pieces of the pixel data supplied in correspondence to each of the plural pixels adjacent to the pixel for the high-order bits of the pixel data D corresponding to every one pixel is inverted or not. This circuit supplies a detection signal P to a changeover control circuit 36. Namely, the circuit changes the light emission patterns to decrease the false contours if any one of the high-order bits of the pixel data varies between the adjacent pixels. The light emission patterns are not changed in the regions where the inversion of the high-order bits of the pixel data does not arise between the adjacent pixels with this constitution and, therefore, the visual recognition of the false contours does not arise even if the moving videos of these parts are traced by the eyes.
